A fast and Accurate Sketch Method for Estimating User Similarities over Trajectory Data. (arXiv:2212.06601v1 [cs.CR])

In a complex urban environment, due to the unavoidable interruption of GNSS
positioning signals and the accumulation of errors during vehicle driving, the
collected vehicle trajectory data is likely to be inaccurate and incomplete. A
weighted trajectory reconstruction algorithm based on a bidirectional RNN deep
network is proposed. GNSS/OBD trajectory acquisition equipment is used to
collect vehicle trajectory information, and multi-source data fusion is used to
realize bidirectional weighted trajectory reconstruction. At the same time, the
neural arithmetic logic unit …
